No they don't. e.g. invertebrates
ALL animals that have a backbone are "vertebrates". ALL animals without a backbone are "invertebrates". Man is an animal with a backbone.
All animals with a backbone are vertebrates. All birds have a backbone. All owls are birds.
No. In fact, it is quite the opposite. 99% of all life on planet Earth are invertebrate, meaning they have no backbone.
These numbers are not accurate, as accurate number of animal species on earth has yet to be discovered. Currently it looks like less than 3% of the known species of animals on earth are vertebrates (have back bones). There are around 50 000 species of vertebrates, most of which are fish. Most animals are invertebrates, and most of those are insects.
No they don't because all worms are invertebrates (animals without a backbone). (:
Animals with a backbone belong to the phylum Chordata. This phylum includes vertebrates such as fish, amphibians, reptiles, birds, and mammals, which all possess a notochord or backbone at some stage in their development.
Insects are the only creatures without backbones. The rest of the other animals in other animal classification all have a backbone.
No, they have a backbone. Vertebrates are ALL animals that have backbones. Invertebrates are ALL animals that do not have backbones.
About 95% of all the animals on earth have no backbone, or spine. They are called invertebrates and range from snails to big, wobbly jellyfish. All invertebrates are cold-blooded -- their body temperature is the same as the air or water around them.
Other animals that do not have a backbone include arthropods (such as insects and spiders), mollusks (such as octopuses and snails), and cnidarians (such as jellyfish and coral). These animals have different types of support structures instead of a rigid backbone.
No, they do not have a backbone, they have an exoskeleton.
Yes. All reptiles are vertebrates. Yes. They are vertebrate animals.
